docs(openrouter-models): sync with openrouter-web changes

[devin-ai-integration]

Summary

openrouter-web #26259 added a new optional input_cache_write_1h field to the public pricing payload on /api/v1/models (and the SDK catalog), surfacing Anthropic's extended 1-hour cache-write rate. input_cache_write now explicitly means the default 5-minute rate.

The openrouter-models skill is the pricing-discovery skill and already emphasizes cache pricing, but its Key Fields table didn't document any of the cache pricing fields. This syncs it:

• Added rows for pricing.input_cache_read, pricing.input_cache_write, and the new pricing.input_cache_write_1h.
• Updated the cache-pricing presenting tip to distinguish the 5-minute (input_cache_write) vs 1-hour (input_cache_write_1h) Anthropic rates.

Docs-only; no script changes.

Original prompt from Automation

You are the public skills sync pipeline. Your job is to scan PRs merged to main on OpenRouterTeam/openrouter-web in the last 24 hours, determine if any changes warrant updating the public agent skills in OpenRouterTeam/skills, and open PRs to the skills repo when updates are needed.

#``# Step 1: Identify relevant merged PRs

Clone both repos:

cd /home/ubuntu/repos/openrouter-web
git fetch origin main
git log --since='24 hours ago' --merges --first-parent origin/main --pretty=format:'%H|%s' --name-only

For each merged PR, collect the list of changed files. Only PRs that touch the paths in the mapping below are relevant. Skip bot commits (devin-ai-integration[bot], Devin AI, GitHub Actions Bot, openrouter[bot], opencode-agent[bot], OpenRouter SDK Bot, Claude, detail-app[bot], forge-the-devex-intern[bot], dependabot[bot]).

If no relevant PRs were merged, post a short message to the #devrel Slack channel (C08LQFVSC7Q) saying no skill-relevant changes were detected today, and exit.

#``# Step 2: Map changed files to affected skills

Use this mapping to determine which public skills are potentially affected:

openrouter-web paths	Affected skill(s) in OpenRouterTeam/skills
sdks/typescript/, packages/llm-interfaces/	openrouter-typescript-sdk, openrouter-agent-migration
services/cfw-*/src/routes/*analytics*, analytics query/response schemas	openrouter-analytics, openrouter-analytics-query, openrouter-analytics-schema
Generation routes, /api/v1/generation	openrouter-generations
Image generation adapters, packages/image-generation/	openrouter-images
supabase/seeds/, model schemas, /api/v1/models route	openrouter-models
OAuth/auth routes, PKCE flow code	openrouter-oauth
STT adapters, services/cfw-stt-api/, /api/v1/audio/transcriptions	openrouter-stt
TTS routes, /api/v1/audio/speech	openrouter-tts
Video adapters, /api/v1/videos	openrouter-video

Perry's Review

Syncs openrouter-models/SKILL.md to document three cache-pricing fields (input_cache_read, input_cache_write, input_cache_write_1h) that were already returned by the API but missing from the Key Fields table.

Verdict: ✅ LGTM
